[edit] Abstract

The PRX functions and call routines are a family of powerful tools to work with text strings. Introduced in Version 9, the PRX functions give you access to the Perl-style regular expressions to match, validate, and replace patterns of text. While many of the traditional character string functions (INDEX, TRANWRD, COMPRESS, etc.) and the LIKE operator can handle many of the trivial text matching and replacement tasks that come your way, the PRX functions shine in the face of the most complicated cases. Though regular expressions offer an immense amount pattern matching capabilities, this paper will cover only the basics of PRX.
